Dropin with supertest #77
Description
While attempting to run an end-to-end test with jest and supertest, I was getting the following error:
TypeError: Invalid URL
After some troubleshooting I realised this is an issue with the ultimate-express application. I switched the application back to a standard express application and with no other changes the tests ran as expected with no exceptions. I have included a dummy application that can recreate this problem.
index.ts
import express from 'ultimate-express';
export default function createApp() {
const app = express();
app.use(express.json());
app.use(express.urlencoded());
app.get('/:name', (req, res): any => {
const name = req.params.name;
return res.status(200).json({hello: name ? `${name}` : 'world'});
})
return app;
}
index.test.ts
import { describe, test, expect } from '@jest/globals';
import request from 'supertest';
import createApp from './index';
const app = createApp();
describe('dummy test', () =>{
test('basic route', async () => {
const name = 'name';
const response = await request(app).get(`/${name}`);
expect(response.status).toEqual(200);
expect(response.body.hello).toBe(name);
})
})
